Question

A labourer is engaged for 15 days on the condition that he will receive 80 rupees for each day he works and he will be fined 10 rupees for each day he is absent. If he receives 570 rupees in all, for how many days did he remain absent?

Answer 1

Define x:

Let x be the number of days he worked.

The number of days that he is absent was (15 - x)

Form equation and solve x:

He earned Rs 80 for each day worked and fined Rs 10 for each day absent

Total amount received = Rs 570

80x -10 (15 - x) = 570

80x - 150 + 10x = 570

90x - 150 = 570

90x = 720

x = 8

Find the number of days he was absent:

Absent Days = 15 - x = 15 - 8 = 7 days

Answer: He was absent for 7 days
